j To all who-m it may concern:

Be it known that 1, WILLIAM A; HAY- milion and State of Indiana, haveinvented certain new and useful Improvements in Car-Couplings,

. of'which the following i a p cification. a j

of car couplers, and morevparticularly to couplers for use with. smallrolling stock such as mine cars, lorries and the like.

One object of my invention is the provlsion ofa coupler which is strongand durable,

not liable to he accidentally released, and. quicklyand safely cou'-pled orluncoupledb an operator. 1 j

Another object 0 the invention is to pro vide a coupler whichcomprisesbut twounits,

thereby providing a single and inexpensive device, with no'loose partsto become lost.

Inthe accompanying drawings the nu f 9 which is provided with the end ofthelink 4 of face thereof, the bottorn'of thispockethav These and otherobjects and. advantages of my invention willbe brought out hereinafterand illustrated in the drawings forming part ofthis specification, andin which-- *igure 1 is a top plan of one ofthe units of my improvedcoupler.

. M a a bottom 11 which inclines downwardly at one This inventionrelates to the construction end (see Fig. 5).

pair'of prongs: or fingers 12 and 13, one on .each side of the slot 8,project forwardly for an appreciable distance, beyond the bottom 11 ofthis slot. The adjacent vertical faces of the slot 8 are parallel withthe ends of the body 2.

The other unit of the coupler comprises a elongated body or'shank 15,the shank having an enlarged rear end 16,. which is provided with'an eye16 that receives' the link 16 of the chain used to se cure the link to acar. This link also is provided on its upper edge with a grip orhandhold 17 that overhangs the forward end of the link (see Fig. 4;). jj The shank or body 15- is also provided lntermediate its ends with apair of cylindrical bearing pins or projections 18, one on each sidethereof, which are adaptedto support the fingers or prongs 12 and 13 ofthe recessed unit 2 when "the two units .or members" are assembled ininterlocking engage- IIlIlt. y j

-Asecond pair of cylindrical pins or projections 19 are integrallyformed with, and adjacent .the forward lower edgeof the shank 15, thecorner 20 of the shank being rounde'd'ofi tocorrespond with thecurvature of the projections. 19. The projections 19 are adapted to fitinto the recess or cavity 5 and to engage in the curve oftheunde'rcutwall 7 thereof. j

j A projecting flange 22 extends outwardly from each side of the shank.15 and extends forwardly beyond the end of the shank 15 to the frontend of the overhanging grip or hand-hold l7. Theprojections-22 are ofsufficient width to. extend beyondthe ends until out of the cavityorpocket 5. When the pins 19-19 are clear of the cavity or pocket 5, theforked link will be disengaged from the opposite link and will'drop, andthe other link is then allowed to fall.

In connecting the links to couple two cars the links are lifted until-inpractically vertical "lengthwise position. The shank 15 is then slippedinto th'e'slot 8 of the forked link 2 and. the fingers 12 and 13 broughtinto engagement with the pins 18. The two links are then lowered untilthe pins 19 rest-in the cavity 5v of the forked link 2 and the wings orflanges 22 engage the upper faces of the link 2. vThe coupler will; thenagain be in the interlocked position shown in Fig. 5.

" The above. described operations will be repeated from time to time inand coupling the links.

'The advantages of my invention which will be appreciated'by thoseskilled in the art arise from the compact construction and absence ofswinging and removable parts.

Various modifications, as will suggest themselves to those skilled inthe art, may be made in the construction of my improved coupler withoutdeparting from the spirit of the invention as defined in the appointedclaims.

I claim I 1. A car coupler comprising in combination separable linksarranged to 'coact in interlocking engagement one with the other andhaving means for attachment thereof to uncoupling the cars, one linkhaving a cavity therein and having fingers onone end thereof, and theother link having projecting pins 'on opposite sides thereof, arrangedto enter said cavity and other projecting pins arranged to engage theunder surfaceof said fingers insecuring the links in interlockingengagement.

2*. A car coupler comprising in combination separable links arranged tocoaot one w th the other, means whereby said l nks are flexiblyconnected to the cars, one link having a recess forming an undercut inits upper 'face and having projecting fingers forming a slot on one endthereof, and the other link having pr'ojecting pins on opposite sidesthereof adapted to enter said undercut cavity and other projecting pinsarranged for engagement with said fingers in connecting the linksineinterloc-king engagement, and one end of said second linkextending'into the slot formed by the fingers on the recessed link.

3. car coupler comprlsing a forked link and coacting link, said forkedlink havinga cavity in the upper face thereof and being slottedlongitudinally, said coacting link having cylindrical projections on thesides thereof adjacent its forward end adapted to enter said cavity insaid forked link, and means for supporting the forward end of saidcoacting link on said forked link.

4. A car coupler comprising in combination separable links arranged tocoact in interlocking engagement one with the other and having means forattachment thereof to the cars, one link having a cavity therein andhaving fingers on one end thereof and the other link having projectingpins on oppositesidesthereof, some of said pins being arranged to entersaid cavity and other of said pins being arranged to engage the undersurface of said fingers in securing the links in interlockingengagement, and means on one end of one link forming a handhold formanipulating said links.

5. A car coupler comprising in combination separable links arranged tocoact in sides of the second link forming flanges engaging the uppersurface of said forked link in connecting the links in coupled relation.

6. A car coupler comprising in combination separable links arranged tocoact in interlocking engagement one with the other and having means forattachment thereof to the cars one link having a cavity therein andhaving fingers on one end thereof and the other link having projectingpins on opposite sides thereof, some of said pins being arranged toenter said cavity and other of said pins being arranged to engage theunder surface of said fingers in securing the links in interlockingengagement, and means on one end of one link forming a handhold formanipulating said links and lugs on the sides of the second link formingflanges engaging the upper surface of said forked link in connecting thelinks in coupled relation, and. an extension on the flanged end of saidother link forming a handheld for manipulating said links.

7 A car coupler comprising, in combination a forked coupler link and acoacting link, said links being adapted to be interlocked, said forkedlink comprising a body portion terminating at its forward end in a pairof fingers and having a cavity in its (upper face provided with aconcave wall,

. support the fingers of said forked link, cy-

lindrical projections on each side of said seciond link at'the forwardend thereof, eXtending outwards therefrom, said projections beingadapted to fit into-the cavity in said forked link, flanges formingshoulders on said second link adapted to overlie the cavity in saidforked link and engage the body thereof, and a hand-hold on said secondlink. r a

8. A car coupler comprising a forked link and a coacting link adapted tobe interlocked, said forked link having a cavity in the upper facethereof, said eoaoting link having a pair of projections on the-sides 20thereof adapted to enter andinterlook with the cavity in said forkedlink, and meansfor preventing said links breaking downwardly beyond ahorizontal plane when interlocked.
